We have learned that journalists have highly selective memories
They could remember any great detail which painted them in a positive light
Their memories let them down over any failings
We learned that they all know of other journalists who have used illegal means of gathering information
All claim they wouldn't do any such thing.
We learned that Newspaper proprietors have their own agendas
We learned they will support anyone who supports their agenda
We learned that Newspaper proprietors lavish extravagant gifts on politicians
We learned that neither parties consider that to be corrupt or likely to earn influence
We learned that eminent QCs can string out questioning long enough to maximise earnings
We learned that all politicians of whichever party behave in the same way when being schmoozed by rich people.

Will we get a better press as a result? - no. Because we get the press we want to pay for (or deserve)
